Player URL possibly invalid

[lkiesow]

The plugin looks for the search service and then uses ${search.service.host}/play/${id} to link to the player. That's not necessarily correct and caused a completely broken plugin for us after the last update:

studip-opencast-plugin/controllers/redirect.php

Lines 36 to 43 in 5a61bb6

	if ($endpoint['service_type'] == 'search') {
	$url = parse_url($endpoint['service_url']);
	$oc_url = $url['scheme'] . '://'. $url['host']
	. ($url['port'] ? ':' . $url['port'] : '');
	$url = $oc_url . '/play/' . $episode_id;

Instead of using the search service, the plugin should actually use org.opencastproject.engage.ui.player.redirect which provides /play. The service should usually be on the presentation node:

❯ curl -s -u admin:opencast 'https://develop.opencast.org/services/services.json?serviceType=org.opencastproject.engage.ui.player.redirect' | jq
{
  "services": {
    "service": {
      "type": "org.opencastproject.engage.ui.player.redirect",
      "host": "https://develop.opencast.org",
      "path": "/play",
      "active": true,
      "online": true,
      "maintenance": false,
      "jobproducer": false,
      "onlinefrom": "2024-09-17T02:00:59.370+02:00",
      "service_state": "NORMAL",
      "state_changed": "2024-09-17T02:00:59.370+02:00",
      "error_state_trigger": 0,
      "warning_state_trigger": 0
    }
  }
}

This also is a problem in the new plugin version
